tumult-BAR.

To all whom it My concern:

Be itkfiown that I, LEWIS P. HALLADAY,

a citizen of the United States, residin at Decatur, in the county ofMacon and tateof Illinois, have invented a certain new and usefulImprovement in Bumper-Bars, of which the following is a specification.

My invention relates to improvements in automobile bumper bars, and hasfor one object to provide a new and improved type of bumper bar in'which two reinforcing spring strips are used, and in which they formapart of the length of the bumper. The widthof the bumper measured in avertical direction is greater than the normal width of the spring stripsof which it is made. Another object is to provide a socalled duplexautomobile bum 'er bar which shall be light, durable and little likelyto break down.

other objects (if my invention, will appear from time to'time in thespecifications.

I illustrate my invention more or less diagrammatically 1n theaccompanying draw in s, wherein:

iigure 1 is a front view of an automobile showing my bumper in place.

Fig. 2 is a plan View of the front end of an automobile and. bumper.

Fig. 3 is a section along the line 33 of Fig. 1.

ike characters are illustrated by like -let- 'ters throughout thespecification.

A 'A are the front frame horns of an automobile frame. porting bracketsattached to said horns. A A are bumper supporting bars projecting fromthe brackets. A 3 are bumper bar supporting yokes carried upon said armsadapted to engage the rear member of a spring bumper bar and hold it inplace.

are identical spring bumper bar elements. It will be noted that they areexactly the same in' size, shape and dimensions, so that when the two ofthem are reversed with respect one to another, they may be put togetherto form the bumper bar which. I have shown.

Each of these spring elements is made up of a generally flat butslightly rearwardly curved front member C of such length as to extendthroughout about one third of tlze total width. In addition to thisthere is a central portion C downwardly or upwardly bent as the case maybe from the portion Specification of Letters Patent. Application filedDecember 1, 1920. -S'erial No.

portions. C C

A A are bumper sup- 0 extending across about another third of thelength. This portion 0 terminates in a. perpendicularly and 'rearwardlyextending portion C from"which projects a back piece C When assembledthese two elements are bolted together by means of the two interiorbolts C C located at'the points where the central portions bend upwardlyor downwardly. as thecase -may be, from the end are" bumper tips or'sockets PATENT or y,

located one at either endofthe bumper bar and the free end of' thebumper springs are held in place in said sockets by the bolts C C. i

It will be noted locked so that the front portion. of the bumper at oneen'd is made out of the same bar as the rear Iportion at theother endand vice versa. T e two bars are. therefore entwined and bolted-togetherand this results in producing a peculiarly rigid and durable structureand one in which sudden distortion cannot result in separating ordisassociatingthe arts. v

While it is evi ent that what I have shown is an operative device, stillmany changes might be made in size, shape and arrangement of partswithout departing from the spirit of my invention.

What I claim is 1. An automobile bumper having a central portioncomprising two flat spring elements arranged one above the other in avertical plane and end portions comprising two ,flat spring elementsarranged one behind the that with the two identi cal bar formingmembers, they can be interend portions comprising two flat springelements arranged "one behindthe other in a horizontal plane, the rearspring element engaging the forward spring element at the ends of thebumper and diverging therefrom toward the center.
